I also tryed to add the "yenta_socket" module to /etc/conf.d/modules:
egeo ~ # tail /etc/conf.d/modules

Code:

# You should consult your kernel documentation and configuration
# for a list of modules and their options.
modules="yenta_socket"

but nothing changed.
I worked around this problem doing the following:
- net.wlan0 service removed from the default runlevel
- wpa_supplicant and dhcpcd services added to the default runlevel
which is probably a dirty trick.

Where am I wrong? Thanks in advance for any suggestions._________________We all smile in the same language
